javascript提取标签之间的信息

     var pt = function (s) {
         document.writeln("<br>" + s);
     };

     var m = "wabc ss ab xx<div><h1>div</h1></div>ss<div>div2</div>";

     function getTagContent(tg){
         var str = "<" + tg + ">(?:(?!<\\/" + tg + ">).)*<\\/" + tg + ">";
         var pttn = new RegExp(str,"g");
         var tmp = this.match(pttn);
         var r = [];
         for(i=0;i<tmp.length;i++){    
             r.push(tmp[i].replace("<"+tg+">","").replace("</"+tg+">",""));
         }
         return r;
     }

     var y = getTagContent.call(m,"div");
     alert(y);
     pt(y);

不支持嵌套结构
输出： <h1>div</h1>,div2
